PAPER MAKING MACHINE Filed Aug- 20, 1928 2 Sheets-Sheet 2 Patented Aug.11, 1931 UNITED STATES PATENT OFFICE EARL E.- BERRY, OF BELOI'I,WISCONSIN, ASSIGNOR T BELOIT IRON WORKS, OF BELOIT, WISCONSIN, ACORPORATION OF WISCONSIN PAPER MAKING MACHINE This invention relates topaper making machines of the Fourdrinier type and has more particularreference to the slice or slices and to features in connectiontherewith. In some respects my invention is an improvement on the papermaking machine claimed in the joint application of Alonzo Aldrich andmyself, Serial No. 194,304, filed May 26, 1927.

The present invention aims to provide a simplified and improvedconstruction for facilitating the making of changes in the deckle widthand at the same time affords a greater range of adjustment of the sliceor slices as the case may be and a consequent regulation 'of the stockwithin a wide range of possibilities and to a fine degree of accu-'racy. The change of deckle widths is made when the machine is at restbut the fine ad-' :0 justments for .controll'ng flow of the stock anddeposit of the fibre may be made while the machine is in operation andin such manner as to afford many practical advantages some of which havetheir foundation :5 in the application above mentioned.

One of the features'of the present invention is the provision of asectional slice having a single lip which is interchangeable with lipsof different lengths corresponding :0 with the slices for difl'erentdeckle widths.

This not only insures a continuous and uninterrupted lip edgecontrolling the final flow of stock to thewire but according to myinvention the lip is flexible and means 5 is provided for adjusting thelip on the sec tional slice so as to vary the depth of flow at pointsalong the length of the lip. As a result of these improvements themachine may be set to meet any of the varying re- D quirementsincidental to the peculiarities of the machine and the particularconditions at hand in respect to the stock and the physicalcharacteristics of the finished sheet.

I have also aimed to provide a construc- 5 tion which will be thoroughlypractical and easy to operate and which will permit the operator toreadily make any such adjustments as may be found necessary or expedientto regulate and control the physical 1 characteristics of the finishedsheet.

Other objects and attendant advantages will be appreciated by thoseskilled in this art as the invention becomes better understood byreference to the following description when considered in connectionwith the accompanying drawings, in which- I Figure 1 is a fragmentaryplan view of a ,head box and slices embodying my invention;

Fig. 2 is a side elevation of such parts; Fig. 3 is a front elevation ofthe main slice removed from the machine; Fig. 4 is a front view of a lipshorter than that shown in Fig. 3;

Fig. 5 is an enlarged vertical section through the slices takensubstantially on the line 55 of Fig. 1; and

Fig. 6 is an enlarged horizontal section taken on the line 6-6 of Fig.2.

In the present illustration of my invention the head box 7 hasstationary pond Sides 8 and what is known as a deckle lift consisting ofpond sides 9 each pivotally mounted at 11 to permit lifting of the sidesand the slices carried thereby when changing the wire and for otherpurposes. The wire is designated by 12, the breast roll by 13 and tablerolls by 14. The apron 15 and the apron board structure 16 may be of anysuitable construction. The open space between the bottom of each pondside 9 and the wire is closed by suitable means such as a spring-pressedside extension plate 20. Each pond side 9 is in the form of .a singleflat plate connected at the points 11 box and may be fixedly secured inany adjusted position by bolts 23, suitable slots being provided in oneorthe other of the connected parts to permit of such adjustment. A tierod in the form of a pipe 24 clamped at its ends by suitable means tothe front end of the pond sides 9 holds them in spaced relation at thisend.

The inside slice consists of two slice plates 25 and 26 in overlappingrelation bolted to gether in a manner well known in this art and adaptedto be lengthened or shortened to take care of different deckle widths.In this case each slice plate is guided at its outer end on a guidebracket 27 which has a top flange 28 seated on the top edge of theadjacent pond side 9 and is adapted to be adjusted lengthwise along thesame by means of a nut 29 and bolt 31 the latter of which connects tothe pond side. A screw 32 threaded in each slice plate at its outer endrests on the adjacent bracket 27 and is adjustable to raise and lowerthe inside slice.

The main slice, in addition to its usual functions, is of suchconstruction as to allow setting for different deckle widths. It alsohas a flexible lip which defines the upper edge of the orifice and isadjustable to regulate and control the flow of stock to. the wire. Thepresent invention meets the problems incidental-to these functions bythe provision of a structure thoroughly practical. In the preferredembodiment of my invention the main slice consists either of a singleplate for the smallest deckle Width or plural plates or sections forgreater deckle widths. As

shown in Figs. 1 and 3 the main slice comprises a central section 33 andend sections 34 each having the same cross-section and disposed in thesame transverse plane. The pre- 35 ferred cross-sectional shape shown inFig. 5 consists of a vertical fiat plate body having a horizontal upperend 35 for stiffening and reenforcing purposes and for providing supportfor a series of lip adjusting rods which 1 will be presently described.The central and end sections, arranged in abutting relation as shown inFig. 3, are secured together by removable coupling plates 36 fastenedby-countersunk-head screws, or otherwise, to'thesections.

equipped with a guide block 37 rabbetted at 37 to receive .aninterfitting guide 38 of a slice-supporting bracket 39 adapted to beclamped to an adjacent pond side 9, as shown in-Fig. 6. The bracket maybe of any suitable or preferred construction. In this instance saidbracket has a flange 41 seating on the top edge of-the pond side andcarries two fixed bolts 42 which extends outwardly through slots 43 inthe pond side. A screw 44 connected to each bolt 42 passes through anoutstanding rug 45 on the pond side and is adapted to be adjustedlengthwise upon and with respect thereto by means of the nuts 46. Bytightening the nuts 47 onthe bolts 42 the bracket 39 will be clamped tothe pond side. A screw 48 threaded in each outer section 34 rests on thetop of' the bracket 39 and is adj ustable to raise and lower the mainslice. In the event that a narrower deckle width is de- Each end sectionat its outer end is.

sired either one or both of the end sections 34 will be removed in whichcase the depth regulating screw or screws 48 will be transposed to athreaded opening 49 in the center slice section and guide bars 37 willbe attached to the outer end or ends of this slice section. In order toeliminate breaks or interruptions in the lower edge of the slice and toprovide for the most effective adjustment of this edge my inventioncontemplates the use of a single lip corresponding in length with theslice and interchangeable with lips of other lengths corresponding withthe different slice lengths. This lip 51, preferably mounted so as toseat against the front face of the slice and be adjustable in the planeof said face, is adapted to be so adjusted by means of a series ofadjusting rods 52 as claimed in the Aldrich and Berry application abovementioned. In the present case the lip has a flange 53 from end to endadapted to be received in a notch 54 in the lower end of each adjustingrod whereby each rod is connecstible to the lip at any point in itslength and may be moved vertically for adjusting the lip. Aspringpressed plate 55 straddles each rod just above the lip and servesto urge the latter yieldingly against the slice, holding it seatedthereon. Each plate 55 is supported at its ends on bolts 56 attached tothe slice plate. Each bolt 56 carries a coiled spring 57 backed againsta nut which is adjustable for varying the pressure of the lip againstthe slice. As shown in Fig. 3 the center slice section is equipped witha series of lip adjusting rods 52, while each end section 34 has only asingle lip adjusting rod. This arrangement, however, is not essential toall applications of my invention. The upper end of each adjusting rod 52is suitably connected to its slice section for vertical adjustmentthereon.

In this instance the rod is threaded into an elongated nut 58 which inturn is threaded into the slice part 35, the internal and externalthreads on the nut 58 being of different pitch so that upon turning saidnut the rod will be raised or lowered as the case may be. It will beobserved that the lip provides a single, continuous, uninterrupted edgefor the sectional slice and that this edge may be so positioned orflexed by adjustment of the rods 52 as to regulate to a fine degree ofaccuracy the depth and shape of the orifice through which the stockflows. This construction also avoids collecting or bunching of thefibers in grooves or joints common to previous constructions. It will beobserved that the lip is of such cross-sectional shape and so mounted inconnection with, the adjusting rods that it may be withdrawn lengthwisefrom its position on the slice when the latter is removed. When removingthe main slice the tension of the springs 37 will be released by backingofi the ins nuts on the ends of the bolts 56 to facilitate thisoperation. The lip 51 shown in Fig. 3, is interchangeable with any otherlip of the same cross-section, a shorter length of lip beingcontemplated for a slice of shorter 34 are removed alip such as 59 shownin Fig. 4, corresponding in length with the center section 33 may besubstituted for the lip 51. In the same way another lip of suitablelength may be substituted in the event that the slice is composed ofonly two sections or of sections of a different length from those shown.

When changing the deckle width it is preferred that the slice-supportingbrackets 39 be removed, together with the slice, as an entirety,whereupon the tension of the springs 57 may be released and the lip maybe withdrawn len thwise from its connection with the adjusting rods.After the slice has been adjusted to the desired length by the additionor removal of sections the new lip may be substituted. When the pondsides 9 have been adjusted laterally to correspond with the'new decklewidth the slice structure may be remounted, as will be obvious.

Adjustment of the inside slice 26 regulates the flow the space betweenthe slices and determines the head of this stock in relation to the headof the pond behind said inside slice. The passing of the stock beneaththe inside slice 26 sets up a turbulence between the slices which tendsto keep the fibers in uniform suspension and to prevent stagnant poolsand Stratification. By adjusting the slices lengthwise *with respect tothe wire and by varying the head of the stock between the slice anydegree of filtration within the [g capabilities of the machine may beobtained.

In addition to this the final flow of the stock onto the wire may beregulated with the greatest precision. The invention in respect to theseadjustments is claimed in the Aldrich and Berry application abovementioned excepting, however, the novel construction herein disclosed. 1I It is believed that the foregoing conveys a clear understanding of myinvention and while I have illustrated but a single embodiment it shouldbe understood that various changesmight be made in the construction andarrangement in various applications without departing from the spiritand scope of the invention as expressed in the appended claims, in whichI claim: 1.
